Marine and Coastal Access Bill [HL]

My Lords, the Minister did not comment on the suggestion that the networks might cover one-third of the sea. I do not know very much about fish, but if these conservation zones cover too big an area, the fish are going to begin to rumble where they can go so as not to be caught. If it were a third of the sea area, I would have thought that Mother Nature and her wonders would mean that the fish would soon discover that they could cluster in that third, and the European fishermen, the Russians and so on would have a very poor time. Does the noble Lord agree?
